Interoperabilidade semântica no contexto de dados da biodiversidade: um estudo de caso sobre a utilização de padrões de metadados

This study deals with the interoperability between different biodiversity information systems, with respect to the description of species occurrence records, with a view to sharing data. The objective of the study was to analyze how the interoperability occurs between informational environments: a) a species occurrence record between iNaturalist (iNat) and Global Biodiversity Information Facility (GBIF) and b) biological interactions data between iNaturalist (iNat) and Global Biotic Interactions (GloBI). The methodological procedures are of exploratory and descriptive objectives, with a qualitative approach, and adopted the single case study technique, analyzing how the semantic interoperability occurs between the selected informational environments. Analyses of the data imported by GBIF and GloBI were carried out, having as origin the data from iNat, highlighting how interoperability occurred between these systems. The results showed that the use of metadata standards allows different information environments to share data among themselves, ensuring semantic interoperability between their metadata. Specifically, between iNat-GBIF and iNat-GloBI, semantic interoperability occurs through the use of metadata standards and controlled vocabularies. The GBIF system automatically recognized and indexed the data record created in iNat with Darwin Core (DwC) metadata. The same was true for GloBI, which automatically recognized and indexed the iNat data record. As a limitation, it is indicated that the metadata analysis was restricted to a small group, leading to the suggestion of future study in a broader scope, also involving other metadata standards.
